Peanut Butter Cheese Fudge

Lightly spray the bottom of a 9 by 2-inch square pan with nonstick cooking spray. In a saucepan over medium heat, melt cheese and butter together, then add peanut butter and stir until smooth. Remove from heat and add vanilla and nuts. Empty confectioner's sugar into a large bowl and pour cheese mixture over sugar. Stir until completely mixed. Candy will be very stiff. Using your hands, remove candy from the bowl and press evenly and firmly into the pan. Because of the amount of butter in this recipe, pat top of candy with a paper towel to remove excess oil. Place the pan in refrigerator until candy is firm. To serve, cut into squares.
